content-pipelines.yml

name: 'Content pipelines: Update content'

# **What it does**: On a schedule, runs the content pipeline update script for each
#   configured entry. The script clones each source repo, detects changes, and
#   runs a Copilot agent to update content articles. The workflow handles
#   branching, committing, and opening PRs.
# **Why we have it**: Keeps reference documentation in sync with upstream source
#   docs without storing copies of those source docs in this repository.
# **Who does it impact**: Docs content writers, docs engineering.
#
# To add a new entry, add it to src/content-pipelines/config.yml and to the matrix
# `include` list below (only `id` is needed). The update logic lives in
# src/content-pipelines/scripts/update.ts, which reads config.yml for all other
# values. Run locally: npx tsx src/content-pipelines/scripts/update.ts --help
